According to police, a 68-year-old man cashed in $2,600 in chips inside the casino Wednesday night. About 3 a.m. Thursday, he drove to his house on Caton Street in Squirrel Hill, where police said it appears he was followed home.

As he got out of his car, he was approached by a man who told him to hand over his money, police said. The man then beat the victim with a metal pipe and took his money, police said.

Investigators said another robbery happened on the fourth floor of the casino's parking garage about 6:30 p.m. Wednesday, when a man claiming to have a gun approached a couple, punched the other man in the chest and took his belongings.

Rivers Casino says it has 1,000 surveillance cameras set up on its property. The casino is working with authorities in the investigation but no suspects have been identified.
